Hey guys! I have a weird problem with my van. I need your advice.
Yesterday morning going to work started the van with no problem drove 32 miles pulled up tp a store and vent in. When I come back and turn the key it sound like the battery is drained. Both speedo mater and tach. slams to the end all lights are out. I checked the battery voltage 12.6v. Remove all the relays and put them back checked all the fuses no problem. Nothing. Go back into the store for 10 min. Come back and it starts right back up. Vent to autozone to get the battery checked and looks like its good. While the van is running I removed negative post van still runs but the interior lights are little flickery.
Its been starting since.
What the hell is going on you guys think?

 

could be as simple as a loose corroded battery cable or terminal?

 

thats what I am thinking too. But not the battery wires I checked both terminals clean and tight since i got the battery new 3 months ago . Btw it did not happen again yet, but now I cant trust the car enough to give it to my wife to drive.

 

When you turned the key and it sounded like the battery was drained, did you get a clicking noise or just silence? could be a park/Neutral safety switch on a fritz?

 

The charging voltage should be around 13.6 or more while the engine is running.If it's not the alternator could be getting ready to die.This should be the voltage even with all the electrics tuned on.If the voltage starts out at the 13.6 and goes down from there as you turn things on then the alternator is very likely the cause.


Here's a couple of links.
